User Agent and Assistive Technology Support Notes

Description

The objective of this technique is to provide a way for users to stop
scrolling content when the scrolling is created by a script. Scrolling
content can be difficult or impossible to read by users with low vision
or with cognitive disabilities. The movement can also be distracting
for some people making it difficult for them to concentrate on other
parts of the Web page.

Examples

Example 1: A toggle button to pause and resume scrolling

In this example, text scrolls from left to right. A toggle button
is provided that allows the user to pause and resume the scrolling
behavior. Additionally, a checkbox is provided which can be used to
slow down the scrolling speed.

Note: Users may prefer a greater variety of scrolling speed options
than are offered in this example. Developers might choose to provide
several speed choices with a slider or drop down list control in order
to accomplish this.

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
